Abstract: In order to satisfy particular design specifications, shape variation for limited geometric envelopes is often employed to alter the elastic properties of flexure joints. This paper introduces an analytical stiffness matrix ...

Abstract: The initiation and development of microcracks (with width generally less than 100–150 μm) introduced by heating or fire plays a critical role in the stability and durability of concrete structures, especially for large ...

Abstract: The punching shear failure of reinforced concrete flat plates has puzzled researchers for a long time due to the complexity of the punching shear mechanism and the difficulty of direct measurements of the internal failure ...

Abstract: When optimizing corrugated flexure (CF) joints, most approaches for calculating the maximum stress on the CF beam depend on finite element analysis (FEA). The current paper introduces the design optimization for joints ...
